SEAT BED Filed April 24, 1957 2 Sheets-Sheet 2 BY MWL YSEAT BED David C.Laemmle, Upper Brookville, N.Y., and Mykola Hawryluk, Bayonne, NJ.,assignors to Bebry Bedding ggrporation, Bayonne, NJ., a corporation ofNew This invention relates to a chair adapted to be converted to a bed.I

fin objectV 'of the invention is to provide a chair in which the backand seat sectionsformthe sections of the bed. Y

Another object of the invention is to provide a chair composed of twopivotally connected sections constituting the back of the chair and aseat section pivotally connected to one of the back sections and whichsections are connected with the chair frame by linkage construction formovement of the sections from the position constituting the back andseat of the chair to an extended position in which the sections aredisposed in alignment to constit'ute a bed.

Another object of the invention is to provide a chair bed in which theparts forming the chair also form parts of the bed.

The invention also provides a chair bed in which the linkage mechanismconnecting the sections together for movement from the chair position tothe bed position are wholly disposed within the chair frame when in thechair position. g

Still another object of the invention is to provide a chair bed which isrigidly supported both in the chair position and in the bed position.

With the foregoing and other objects in view, reference is now made tothe following specification and accompanying drawings in which thepreferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a top plan view of a chair bed combination constructed inaccordance with the invention. Y

Fig. 2 is a longitudinal sectional view taken approximately on line 2 2of Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing the sections partly swungtowards the chair position.

Fig. 4 is a similar view showing the sections in the chair position.

Fig. 5 is an enlarged fragmentary sectional view ltaken approximately online 5-5 of Fig. 1.

Fig. 6 is a sectional view taken approximately on line 6 6 of Fig. 5.

Referring to the drawings, the chair bed includes a base frame 10consisting of opposite side panels 11 and 12, a front panel 13, a crossmember 14 connected between the side panels 11 and 12 adjacent lthe rearthereof and suitable legs 15 and 16 rigidly aixed to said frame.

Swingably connected with the base frame 10 are a plurality of sections17, 18 and 19 constituting the back and seat portions of the chair whenin the chair position and which provide bed forming sections when in thebed position. The sections 17, 18 and 19 are upholstered, the upholsteryextending in continuous formation enclosing the sides and top of thesections whereby the joints between the sections are hidden from viewand the sections have relative movement from one position to the otherwithout stress on the upholstery. The upholstery consists of fillingmaterial 20 supported onsprings aixed ,Hired Stews Patent O 2,937,332retenes May 24.A 1960 `2 to the sections and with a suitable covering 21enclosing the filling material and secured to the under side'of thesections.

The sections 17, 18 and 19 are preferably of wooden or equivalentconstruction, the section 17 including oppositely disposed side rails 22and 23, an end rail 24 and sinuous bed springs 2S affixed at their endsto the side rails of the section. The section 18 also consists of siderails 26 and 271, an end rail 28 and sinuous bed springs 29 affixed attheir ends to the siderails of the section.

The side rails of the said sections are disposed in end` to end relationand are swingably vconnected together at each side on pivot pins 31 and32 extending through the ends of a curved metal element 33 and throughat bars 34 and 35 ali-ixed to theinside faces of the confronting ends ofthe side rails. The inner faces of the side rails are cut away toprovide clearances between the pivoted ends of the flat bars 34 and 35and the side rails so as to accommodate the curved metal elements 33.The pivot pins 3-1 extend through the lower longitudinal edge portion ofthe dat bars 34, while the pivot pins v32 extend through the upperlongitudinal edge portion of the hat bars 35.k The confronting ends ofthe said side rails are also connected by av transversely extendingU-shaped frame member 36 having upstanding legs 37 at the ends thereof.lThe legs 37 are formed with upstanding projections through which extendpivot pins 38 and 39 pivotally connecting the frame member 36 with theat bars 34 Vand 35. The pivot pins 38 extend through the ilat bars 34respectively and through one ofthe projections of eachof the legs, whilethe pivot pins 39 extend through the liat bars 35 respectively andthrough the other -projection of each of the legs. By this arrangementthe frame member 36 rests upon the upper edge of the front panel 13Y ofthe base frame 1t) when the sections are in bed forming relation tothereby support the confronting ends of the bed sections 17 and 18 uponthe base frame 10 when in the bed forming relation,

The section 19 includes side rails 41 and 42, opposite end rails 43 and44 and sinuous springs 45 aixed at their ends to the siderails of thesection. The said section is swingably connected with the section 18 andis supported at its outer end by legs 46. The legs are pivoted to thesection 19 on pivot pins 47 extending through angle bars 48 aliixed tothe underside of the side rails 41 and 42 thereof. y l y vA linkageconstruction is connected at each side with the legs 46 and with thesections 17, 18 and 19 and the base frame 10 for swinging the legs tocollapsed relation with the outer section 19 with the movement of thesections 17, 18 and 19 from the bed forming relation to the seat formingposition; The said linkage construction at each side includes a link 50which is pivotally connected at its forward end to the free upper end ofone of the legs 46 on a pivot pin 52 and Aat its other end the said linkis curved upwardly and is pivotally connected to a link 53 on a pivotpin 54. "The link 53 is pivotally connected to the projecting inner endof one of the angle bars 48 on a pivot pin 55 and the other end of thelink 53 is pivotally connected to a bent link 56 on a pivot pin 57. Thebent links 56 are pivotally connected at their lower ends on pivot pins58 to flat metal straps 59 affixed `to the inside faces of the sidepanels of the base frame 10.

The section 17 is swingablyV connected with the base frame 10 on pivotpins 60 extending through the inner ends of the straps 59 and throughbrackets 61 ailixed to the under side of the said section. Links 62 arepivoted to the brackets 61 on pivot pins 63 located in spaced relationto the pivot pin 60 to provide leverage for moving the links 62rearwardly and forwardly with the movement of the section 17 to and fromthe bed forming position. The forward ends of the 62 arepivoted toaesassa cam members 64 on pivot pins 65 respectively. The cam members 64are pivoted to the straps 59 on pivot pins 66 for rotary movement withthe movement of the links 62. The section 17 is biased toward the chairforming positionby coiled springs 67 which are attached to lugs 68 aixedto the brackets 61. The forward ends of the springs are attached to theupper ends of links 69 pivoted on pivot pins 70 to brackets 71 aiiixedto the straps 59. The lower ends of the last mentioned links areconnected with the bent links 56 by links 72, which latter links arepivoted to the links 69 and to the bent links 65 on pivot pins 73 and74. This construction biases the movement of the section 19 towardsupported engagement on the base frame 10. The bent links 56 areprovided with lugs 75 which engage against the downturned forward endsof the straps 59 to limit the forward movement of the bent links. Thecam members 64 have cam peripheral edges 76 which engage the lugs 75 andcam the same against the downturned ends of the straps 59 and retain thebent links 56 in the forward position when the sections are in the bedforming relation, thus locking the sections in the bed forming relation.The bent links 56 being retained in said forward position when thesections are in bed forming relation as shown in Fig. 2 of the drawings,the links 53 swing about the pivotal connections 57 with said bent linkswhen the seat section 19 is elevated in the movement of the sections tochair formation. With the movement of the back section 17 toward theupstanding relation shown in Fig. 3 of the drawings, the cam members 64are moved out of cammed engagement with the bent links 56 whereupon thebent links swing about the pivots 58 from the forward position to aninverted position with the continued movement of the seat section towardseatI relation whereby the links 53 swing downwardly to dispose thesection 18 in adjacent relation with the back section 17. With the bentlinks 56 disposed forwardly, the springs 67 function to swing theadjacent ends of the back sections 17 and 18 upwardly about theirpivotal connections with the transversely extending member 36 with theinitial upward movement of the seat section 19 toward seat relation.

Constructed in this manner, the section 17 abuts against the rear endsof the side panels 11 and 12 of the base frame when the said section isin the chair forming position. The section 18 abuts against the section17 at the sides thereof when in the chair forming position and thesection 19 rests upon the upper edges of the side panels 11 and 12 ofthe base frame 10 when the sections are in the chair forming position.

In order to move the sections from the chair forming position to the bedforming position, the section 19 is raised and pulled forwardly so as toswing the sections into end to end horizontal alignment, which movementfunctions to move the legs 46 from collapsed relation with the section19 to the upright relation for supporting the outer end of the saidsection. When in this position, the springs 67 are under tension so asto assist in the rearward swinging of the section 17.

While the preferred form of the invention has been shown and describedherein, it is to be understood that the same'is not so limited but shallcover and include any and all modifications of the invention which fallwithin the purview thereof.
